Record and analyze the Results: What happened or didn't happen? Create tables and charts to keep track of your results as you conduct your experiment: Example of a data chart:
*You can also include drawings, pictures, diagrams to help you keep track of the results of your experiment. Once you have finished collecting your data it is time to create a graph to help analyze (study) the results. *Remember that it is a GOOD idea to run trials three times and take an average if your experiment has increments (changes in steps). Graph your results so that you will be able to draw conclusions. The Independent Variable does along the X Axis and the Dependent Variable goes along the Y axis. Make sure to make a different graph for each dependent variable you observed or measured. Graphs should have titles, labeled axis, and the increments should be even. *Below is an Example of a Graph where the Independent Variable was changed in increments (changes in steps). Ray length was measured at 4 different drop heights (3 averaged trials per different height). Dependent Variable (Y Axis) Variable Measured or Observed
Independent Variable (X Axis) Variable Changed
*Below is an Example of a Graph where the Independent Variable wasn't changed in increments (steps). The measurements were recorded on different days.
Dependent Variable (Y Axis) Variable Measured or Observed
Independent Variable (X Axis) Variable Changed *If your experiment does not generate numbers to graph (Dependent Variable) you may make up a scale so that you can graph, for example: (make up your own scale depending on the experiment and type of observations):
Once you have created all your graphs and can see all your data it's finally time to draw CONCLUSIONS:
